BRUSH AND MOD OF MAKING THE SAME.

SPECIFICATION forming part of Letters Patent Iva/130557, dated June 17, 1890.

Application nea october 4,1889.

T all whom it may concern:

Beit known' that I, ARTHUR H. WoLooTT,

a citizen of the United States, and a resident of Vinthrop, in the county of Suffolk and State of Massachusetts, have invented new and useful Improvements in Brushes and Mode of Making the Same, of which the following, taken in connection with the accompanying drawings, is a specification.

This invention relates to that type of brushes wherein the bristles are secured in a shouldered ferrule and an independent handlecarrying shell is secured to the ferrule. In the prior construction the ferrule and shell I5 are screwed together, and consequently they are necessarily true circles in cross-section, which limits the construction to a cylindrical brush.

The object of my inventipn is to improve 2o the prior devices by providing such constructionvthat brushes which are fiat or oblong in cross-section are produced and screw-threads are avoided. To accomplish this object my invention involves the features of construc- 2 5 tion and the combination or arrangement of parts hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l is a side elevation of a brush em- 3o bodying my invention. Fig. 2 isalongitudinal section of the same. Fig. 3 is a vertical section on the line Qc 0c, Fig. 1. Fig. #i is a perspective vieT showing the parts of the brush separated.

Similar letters refer to similar parts wherever they occur on the different parts of the drawings.

In the drawings, the letter c indicates the metal ferrule, in which the bristles h b are se- 4o cured in any well-known or suitable manner,

this ferrule abeing in one piece with the upwardly-proj ectin g neck or extension a', which is slightly reduced in diameter to forni an internal and external offset ct,as shown. In connection with the ferrule a, c', I use the flattened metal shell c, open in its lower end and having attached to its upper end the Serial No. 326,601. (No model.)

flanged cap c', to which is soldered .a metal handle-socket c for receiving the handle d.

'In making the improved brush the bristles bb are inserted and fastened in the ferrule a, after which the reduced portion a" of said ferrule is inserted into the lower end of the shell c, and the said shell and ferrule are soldered together at the shoulder or offset a, thus producing a very neat and strong union between the parts mentioned.

The reduced tubular neck c. is smooth on its exterior surface to easily slide into the smooth interior of the independent handlecarrying shell, whereby a brush can be produced which in cross-section is -iiattened or of any outline desired. This result cannot be attained where the ferrule and shell are screwed together, and therefore I do not claim the latter construction.

The reduced neck a is formed by compression of the metal in such manner that the offset a is inside as well as outside the ferrule, and thus the internal shoulder abuts the bristles and the reduced neck compresses the butt-ends of such bristles, the construction being such as to produce brushes which are fiattened or oval in cross-section.

Having thus described my invention, what I claim is- A flattened brush consisting of a ferrule flattened in cross-section and having the internal and external offsetand the reduced externally-smooth neck to compress the buttends o f the bristles inserted therein, and the` independent handle-carrying shell flattened in cross-section and having an internallysmooth portion slipped over the reduced smooth neck of the ferrule and soldered thereto, substantially as described.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 26th day of September, A. D. 1889.

ARTHUR H. VOLCOTT.
